DETAILED DESCRIPTION

Example arrangements will now be described more fully with reference to the accompanying drawings. However, example arrangements can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these arrangements are provided so that the present disclosure will be more comprehensive and complete, and will fully convey the concept of the example arrangements to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more arrangements.

Moreover, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily have to correspond to physically or logically independent entities. These functional entities may be implemented in software, or implemented in one or more hardware modules or integrated circuits, or implemented in different network and/or processor devices and/or microcontroller devices.

The present example arrangement provides an assistive fitness system that can be placed in front of the exercise area, to collocate with the exercise equipment to assist a fitness person in exercising. As shown in FIG. 1 and FIG. 2, the assistive fitness system may include:

a thermal imaging device 10, configured to receive an infrared signal from a human body and perform thermal imaging processing based on the infrared signal to generate a human body image;

a comparing device, configured to compare the human body image with a reference image of a standard fitness movement to generate a comparison result; and

a display device 20, configured to display the human body image and the comparison result of the human body image and the reference image.

In this arrangement, the display device 20 can display the human body image generated by the thermal imaging process and the comparison result of the human body image and the reference image in a nested manner. That is, while the human body image is displayed, the comparison result is nested with the human body image in a line outline manner for display. The exemplary arrangement is not limited thereto. The display device 20 may include any one of an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode), and a PDP (Plasma Display Panel), not limited to this.

It should be noted that the thermal imaging device 10 may be an integrated device or may be a device composed of a plurality of components. In one arrangement, the thermal imaging device 10 shown in FIG. 1 may be a receiving unit for receiving an infrared signal, and the thermal imaging device 10 shown in FIG. 2 may be a processing unit for performing thermal imaging processing. The infrared signal received by the receiving unit can be sent to the processing unit for processing by wired or wireless communication. The present disclosure does not limit the specific arrangement and position of the thermal imaging device 10.

In the assistive fitness system provided by the exemplary arrangement of the present disclosure, by adding a thermal imaging device, a comparison device, and a display device, thermal imaging processing may be performed on a fitness person, to generate a corresponding human body image and compare the human body image with a reference image of a standard fitness movement, so as to present the comparison result in the display device. In this way, the fitness person can not only observe whether his own movement is standard through the comparison result presented by the display device, but also can observe a movement state of the muscle, so as to avoid physical injury caused by wrong movement or excessive exercise.

The assistive fitness system provided in this exemplary arrangement will be described in detail below with reference to the accompanying drawings.

In this exemplary arrangement, as shown in FIG. 3, the thermal imaging apparatus 10 may include:

an optical module 101, configured to receive an infrared signal from a human body and focus the infrared signal to a focal plane of the optical module 101;

a thermoelectric sensor 102, disposed at a position of the focal plane and configured to extract a thermal signal in the infrared signal and convert the thermal signal into an electrical signal; and

a conversion circuit 103, connected to the thermoelectric sensor 102 and configured to acquire the electrical signal and process the electrical signal to convert the electrical signal into an image signal.

In the arrangement, the conversion circuit 103 may include an analog circuit 1031, an A/D (Analog-to-Digital) converter 1032, a digital signal processor (DSP) 1033, and a D/A (Digital-to-Analogue) converter 1034 successively connected.

In this way, the infrared signal radiated by the fitness person is received by the optical module 101 and focused on the thermoelectric sensor 102 located at the focal plane. The thermoelectric sensor 102 extracts a thermal signal in the infrared signal and converts the thermal signal into an electrical signal for transmission to the conversion circuit 103. The analog circuit 1031 in the conversion circuit 103 acquires the above electrical signal and performs processing such as amplification and noise removal, and then converts it into a signal that can be acquired by the A/D converter 1032. Then, through the A/D converter 1032, the analog signal is converted into a digital signal for transmission to the DSP processor 1033 for image processing. The processed digital signal is then transmitted to the D/A converter 1034 to be converted into an analog signal, and the converted analog signal is finally presented on the display device 20 for human viewing.

It should be noted that the thermoelectric sensor 103 may be a pyroelectric sensor or a general thermoelectric sensor.

In this exemplary arrangement, as shown in FIG. 4, the thermal imaging apparatus 10 may further include:

a monitoring module 104, configured to monitor a muscle state of the human body in real time and judge whether a current muscle state reaches an exercise saturation state automatically; and

an alerting module 105, connected to the monitoring module 104 and configured to issue an alert when the current muscle state reaches the exercise saturation state.

In this way, the thermal imaging device 10 can determine the muscle state of the fitness person in real time, and issues a prompt when reaching an exhausted or saturated state, so that it can effectively prevent muscle strain and even more serious damage caused by excessive exercise.

In the present exemplary arrangement, the assistive fitness system may further include a communication device, connected to the display device 200, and configured to acquire a reference image of the standard fitness movement for transmission to the display device 20.

In this case, the display device 20 may include the display device includes a first display area and a second display area. The first display area may be used to display a human body image generated through the thermal imaging process and a comparison result of the human body image and the reference image. The second display area may be used to display the reference image of the standard fitness movement.

In one arrangement, the first display area and the second display area can be set to be left and right side by side, so that the fitness person can compare his own movement with the standard fitness movement to timely correct the wrong movement.

Based on the above arrangements, referring to FIG. 1 and FIG. 2, the assistive fitness system may further include:

a far infrared generating device 30, configured to generate a far infrared light and irradiate to the human body, so that resonance absorption occurs in the human body;

a bracket 40, configured to adjust a height of the far infrared generating device 30, so that the human body is located in a far infrared imaging area of the far infrared generating device 30.

In the arrangement, the far infrared light generated by the far infrared generating device 30 has a wavelength range greater than or equal to 4 μm.

It should be noted that the resonance absorption means that a frequency of the far infrared light generated by the far infrared generating device 30 is close to a vibration frequency of cellular molecules in the human body, and thus is easily absorbed by the human body to generate a resonance phenomenon. In the present arrangement, the infrared wavelength of natural radiation of the human body is about 10 μm, and the far infrared light greater than or equal to 4 μm is generated by the far infrared generating device 30, which is advantageous for the resonance absorption of the human body. In another arrangement, when the far infrared light generated by the far infrared generating device 30 has a wavelength of 9.4 μm, the resonance absorption occurred in the human body achieves an optimum effect.

In this way, the resonance absorption may occur due to the far infrared light illuminating the human body, and on one hand, substances which are likely to cause fatigue and aging, such as lactic acid, free fatty acid, cholesterol, excess subcutaneous fat, etc., may be metabolized directly at the skin without using kidney by the activity of the follicular orifice and under subcutaneous fat, thereby alleviating the fatigue caused by exercise and effectively prolonging the exercise time; on the other hand, the oxygen content of the blood can be increased, thereby improving the efficiency of aerobic exercise; on another hand, the heat energy in the body can also be improved, in order to activate the cells, thereby promoting the metabolism and combustion decomposition of the adipose tissue, in order to consume excess fat.

Based on this, the assistive fitness system may further include a control system 50 in communication with the bracket 40, for automatically controlling the lifting and lowering of the bracket 40.

Still further, the assistive fitness system may further include a housing 60, disposed above the bracket 40 and connected to the bracket 40, for placing the thermal imaging device 10, the display device 20 and the far infrared generating device 30 or the like. In this way, by adjusting the height of the housing 60, the bracket 40 may adjust the height of the far infrared generating device 30.

In this exemplary arrangement, as shown in FIG. 5, the far infrared generating device 30 may include:

a far infrared generating unit 301, configured to generate a far infrared light with a wavelength greater than or equal to 1 μm;

a filtering unit 302, configured to perform filter processing on the far infrared light, so as to control the wavelength of the far infrared light to be greater than or equal to 4

a regulating unit 303, configured to perform energy regulation on the far infrared light; and

an executing unit 304, configured to apply the far infrared light subjected to the filter processing and the energy regulation to the human body, so as to achieve an assistive fitness effect.

Based on this, it can be seen that the far infrared light ultimately acting on the human body has a band and energy suitable for reception by the human body. Such far infrared light irradiating to the human body can at least achieve following effects: first, expanding microvessels, promoting blood circulation, rejuvenating enzymes, and strengthening blood and cell tissue metabolism; second, relaxing muscles, driving exchange of oxygen and nutrient in microvascular networks, and eliminating fatigue and aging substances accumulated in the body to remove internal swelling; and third, increasing blood oxygen content. In this way, by generating suitable far infrared light to illuminate the human body, the present arrangement can not only prolong the exercise time significantly, but also accelerate the exercise consumption and keep body healthy.

The example arrangement also provides an assistive fitness method. As shown in FIG. 6, the assistive fitness method may include:

S1, receiving an infrared signal from a human body and performing thermal imaging process based on the infrared signal to generate a human body image;

S2, comparing the human body image with a reference image of a standard fitness movement to generate a comparison result; and

S3, displaying the human body image and the comparison result of the human body image and the reference image.

In the assistive fitness method provided by the exemplary arrangement of the present disclosure, thermal imaging processing may be performed on a fitness person, to generate a corresponding human body image and compare the human body image with a reference image of a standard fitness movement, so as to present the comparison result in the display device. In this way, the fitness person can not only observe whether his own movement is standard through the comparison result presented by the display device, but also can observe a movement state of the muscle, so as to avoid physical injury caused by wrong movement or excessive exercise.

In this exemplary arrangement, as shown in FIG. 7, the assistive fitness method may further include:

S4, irradiating a far infrared light to the human body, so that resonance absorption occurs in the human body.

In this way, the resonance absorption may occur due to the far infrared light illuminating the human body, and on one hand, substances which are likely to cause fatigue and aging, such as lactic acid, free fatty acid, cholesterol, excess subcutaneous fat, etc., may be metabolized directly at the skin without using kidney by the activity of the follicular orifice and under subcutaneous fat, thereby alleviating the fatigue caused by exercise and effectively prolonging the exercise time; on the other hand, the oxygen content of the blood can be increased, thereby improving the efficiency of aerobic exercise; on another hand, the heat energy in the body can also be improved, in order to activate the cells, thereby promoting the metabolism and combustion decomposition of the adipose tissue, in order to consume excess fat.

It should be noted that specific details of the assistive fitness method have been described in detail in the corresponding assistive fitness system, and will not be repeated here.

Based on this, the present exemplary arrangement further provides a fitness equipment including the above-mentioned assistive fitness system. In the arrangement, the assistive fitness system is arranged in front of the exercise area and can collocate with the exercise equipment to assist a fitness person in exercising.

In one arrangement, the assistive fitness system may be disposed directly in front of the treadmill, and the far infrared generating device 30 may be adjusted to an appropriate height by controlling the lifting and lowering of the bracket 40, so as to ensure that the human body is located in the far infrared imaging area of the far infrared generating device 30.

It should be noted that although several modules or units of the apparatus for action execution are mentioned in the above detailed description, such division is not mandatory. In fact, according to arrangements of the present disclosure, features and functions of two or more modules or units described above may be embodied in one module or unit. Conversely, the features and functions of one module or unit described above may be further divided into a plurality of modules or units for embodying.

Moreover, although various steps of the method in the present disclosure have been described in a specific order in the drawings, this does not require or imply that these steps must be performed in this particular order, or all illustrated steps must be performed to achieve the desired result. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and/or one step may be broken down into multiple steps for executions.
